 1.51  07-Sep-2021  riastradh sys/compat: Memset zero before copyout.

Just in case of uninitialized padding which would lead to kernel
stack disclosure. If the compiler can prove the memset redundant
then it can optimize it away; otherwise better safe than sorry.
 1.50  03-May-2017  chs branches: 1.50.2; 1.50.14;
add missing arg to fpu_discard().
 1.49  16-Mar-2017  chs branches: 1.49.4;
allow pcu_save() and pcu_discard() to be called on other threads,
ptrace needs to use it that way.
 1.48  09-Nov-2014  maxv branches: 1.48.2; 1.48.4; 1.48.6;
Do not uselessly include <sys/malloc.h>.
 1.47  27-Jan-2013  mbalmer branches: 1.47.12;
exitting -> exiting.
 1.46  05-May-2011  matt branches: 1.46.4; 1.46.14;
Adapt to new PCU based FPU code.
 1.45  20-Jan-2011  he save_fpu_lwp() was renamed to fpu_save_lwp(), so follow suit.
 1.44  18-Jan-2011  matt branches: 1.44.2;
Deal with changes in the trapframe.
 1.43  14-Jan-2011  rmind branches: 1.43.2;
Retire struct user, remove sys/user.h inclusions. Note sys/user.h header
as obsolete. Remove USER_TO_UAREA/UAREA_TO_USER macros.

Various #include fixes and review by matt@.
 1.42  07-Jul-2010  chs many changes for COMPAT_LINUX:
- update the linux syscall table for each platform.
- support new-style (NPTL) linux pthreads on all platforms.
clone() with CLONE_THREAD uses 1 process with many LWPs
instead of separate processes.
- move the contents of sys__lwp_setprivate() into a new
lwp_setprivate() and use that everywhere.
- update linux_release[] and linux32_release[] to "2.6.18".
- adjust placement of emul fork/exec/exit hooks as needed
and adjust other emul code to match.
- convert all struct emul definitions to use named initializers.
- change the pid allocator to allow multiple pids to refer to the same proc.
- remove a few fields from struct proc that are no longer needed.
- disable the non-functional "vdso" code in linux32/amd64,
glibc works fine without it.
- fix a race in the futex code where we could miss a wakeup after
a requeue operation.
- redo futex locking to be a little more efficient.
 1.41  02-Feb-2010  wiz branches: 1.41.2; 1.41.4;
Missing printf in sys/compat/linux/arch/powerpc/linux_machdep.c
found by cppcheck and reported by Henning Petersen in PR 42720.
 1.40  23-Nov-2009  rmind Use lwp_getpcb() in compat code, clean from struct user.
 1.39  28-Apr-2008  martin branches: 1.39.2; 1.39.22;
Remove clause 3 and 4 from TNF licenses
 1.38  24-Apr-2008  ad branches: 1.38.2;
Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since
we no longer need to guard against access from hardware interrupt handlers.

Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the
child process share the parent's lock so that signal state may be kept in
sync. Partially addresses PR kern/37437.
 1.37  20-Dec-2007  dsl branches: 1.37.6; 1.37.8;
Convert all the system call entry points from:
int foo(struct lwp *l, void *v, register_t *retval)
to:
int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.
 1.36  08-Dec-2007  dsl branches: 1.36.4;
ANSIfy most of the function definitions in sys/compat (but not ndis).
All by the magic of sed ...
 1.35  19-Oct-2007  ad branches: 1.35.4;
machine/{bus,cpu,intr}.h -> sys/{bus,cpu,intr}.h
 1.34  05-Mar-2007  tsutsui branches: 1.34.2; 1.34.14; 1.34.16; 1.34.20;
Use (char *) cast on pointer arith.
 1.33  04-Mar-2007  christos Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.32  09-Feb-2007  ad branches: 1.32.2;
Merge newlock2 to head.
 1.31  11-Dec-2005  christos branches: 1.31.20;
merge ktrace-lwp.
 1.30  20-May-2005  fvdl branches: 1.30.2;
Define linux_usertrap function, and set it in struct emul. For all
but amd64, it just returns 0, doing nothing.

For amd64, it implements vsyscalls through cheating: if the faulting
address is in the vsyscall area (which is statically known on Linux/amd64),
and the intruction pointer is too, it must have been a vsyscall. In that
case, retrieve the return address from the user stack, fix up %rip and
%rsp, and just execute the normal system call. It will return as if
the vsyscall has been executed.
 1.29  26-Feb-2005  perry nuke trailing whitespace
 1.28  17-Apr-2004  matt branches: 1.28.4; 1.28.6;
Switch to using PSL_USEROK_P()
Use new save_fpu_lwp sematics to save or discard the fpu state appropriately.
 1.27  26-Mar-2004  drochner all ports define __HAVE_SIGINFO now, so remove the CPP conditionals
 1.26  08-Oct-2003  thorpej Use ksi_signo accessor macro.
 1.25  26-Sep-2003  simonb Fix "constify sendsig/trapsignal" fallout for non-siginfo'd archs. Test
compiled on most architectures.
 1.24  25-Sep-2003  christos constify sendsig/trapsignal
 1.23  25-Sep-2003  matt Add siginfo support for PowerPC.
 1.22  29-Jun-2003  fvdl branches: 1.22.2;
Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
 1.21  29-Jun-2003  darrenr 'struct proc *' -> 'struct lwp *' as required to get GENERIC for macppc built
 1.20  18-Jan-2003  thorpej Merge the nathanw_sa branch.
 1.19  25-Sep-2002  thorpej Don't include <sys/map.h>.
 1.18  28-Jul-2002  chs restructure the FPU and AltiVEC code so that it works for MP.
 1.17  09-Jul-2002  matt Change fpuproc to curcpu()->ci_fpuproc.
 1.16  04-Jul-2002  thorpej Add kernel support for having userland provide the signal trampoline:

* struct sigacts gets a new sigact_sigdesc structure, which has the
sigaction and the trampoline/version. Version 0 means "legacy kernel
provided trampoline". Other versions are coordinated with machine-
dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions. Instead,
sendsig() looks up the handler by peeking in the sigacts for the
process getting the signal (since it has to look in there for the
trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
its arguments based on the trampoline version in the sigacts.

Changes to libc to use the new facility will be checked in later. Kernel
version not bumped; we will ride the 1.6C bump made recently.
 1.15  20-May-2002  jdolecek whitespace fixes
 1.14  31-Mar-2002  christos branches: 1.14.2;
make signal array handling uniform, and put signal arrays in a separate
file. This is simular to errno array handling.
 1.13  15-Feb-2002  christos - add a real linux_sys___sysctl because the mib numbers are different.
implement only the kernel version getting entries.
- make the signal conversion functions consistent; dest is arg 1.
- make linux_fakedev deal with block and char devices differently.
- add linux_sys_ugetrlimit, and flesh out the regular get/setrlimit so
that they work properly.
- add linux_mmap2 [untested].
- bump kernel to 2.4.18, and make the date be valentine's day :-)
- linux_sys_*stat64 family was totally busted. Fix it.

tested only on i386.

Status:
gdb, telnet, work
jdk-1.4.0 extractor works, jdk still coredumps.

 1.39.22.1  07-Jan-2011  matt Deal with the trapframe changes.
 1.39.2.3  14-May-2008  wrstuden Per discussion with ad at n dot o, revert signal mask handling
changes.

The l_sigstk changes are most likely totally un-needed as SA will
never use a signal stack - we send an upcall (or will as other
diffs are brought in).

The l_sigmask changes were too controvertial. In all honesty, I
think it's probably best to revert them. The main reason they were
there is the fact that in an SA process, we don't mask signals per
kernel thread, we mask them per user thread. In the kernel, we want
them all to get turned into upcalls. Thus the normal state of
l_sigmask in an SA process is for it to always be empty.

While we are in the process of delivering a signal, we want to
temporarily mask a signal (so we don't recursively exhaust our
upcall stacks). However signal delivery is rare (important, but
rare), and delivering back-to-back signals is even rarer. So rather
than cause every user of a signal mask to be prepared for this very
rare case, we will just add a second check later in the signal
delivery code. Said change is not in this diff.

This also un-compensates all of our compatability code for dealing
with SA. SA is a NetBSD-specific thing, so there's no need for
Irix, Linux, Solaris, SVR4 and so on to cope with it.

As previously, everything other than kern_sa.c compiles in i386
GENERIC as of this checkin. I will switch to ALL soon for compile
testing.
 1.39.2.2  14-May-2008  wrstuden Per discussion with ad, remove most of the #include <sys/sa.h> lines
as they were including sa.h just for the type(s) needed for syscallargs.h.

Instead, create a new file, sys/satypes.h, which contains just the
types needed for syscallargs.h. Yes, there's only one now, but that
may change and it's probably more likely to change if it'd be difficult
to handle. :-)

Per discussion with matt at n dot o, add an include of satypes.h to
sigtypes.h. Upcall handlers are kinda signal handlers, and signalling
is the header file that's already included for syscallargs.h that
closest matches SA.

This shaves about 3000 lines off of the diff of the branch relative
to the base. That also represents about 18% of the total before this
checkin.

I think this reduction is very good thing.
 1.39.2.1  10-May-2008  wrstuden Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

Do not uselessly include <sys/malloc.h>.
Cleanup:
- remove struct kmembuckets (dead)
- correctly deadify MALLOC_XX
- remove MALLOC_DEFINE_LIMIT and MALLOC_JUSTDEFINE_LIMIT (dead)
- remove malloc_roundup(), malloc_type_setlimit(), MALLOC_DEFINE_LIMIT()
and MALLOC_JUSTDEFINE_LIMIT() from man 9 malloc
New sentence, new line. Bump date for previous.
Obsolete malloc_roundup(9), malloc_type_setlimit(9) and MALLOC_DEFINE_LIMIT(9)
man pages.

sys/compat: Memset zero before copyout.

Just in case of uninitialized padding which would lead to kernel

then it can optimize it away; otherwise better safe than sorry.
